74ALVCH162827
20-bit buffer/line driver; non-inverting; with 30 Ohm termination resistors; 3-state
The 74ALVCH162827 is a 20-bit buffer/line driver with bus hold inputs, 30 Ω termination resistors and 3-state outputs. The device can be used as two 10-bit buffers or one 20-bit buffer. The device features output enable (nOE1 and nOE2) inputs, each controlling 10-bits. A HIGH on either nOE1 or nOE2 causes the outputs to assume a high-impedance OFF-state. This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
Features and benefits
CMOS low power dissipation
MULTIBYTE™ flow-through standard pin-out architecture
Low inductance multiple VCC and GND pins for minimum noise and ground bounce
Direct interface with TTL levels (2.7 V to 3.6 V)
Bus hold on data inputs
Current drive ± 12 mA at 3.0 V
Integrated 30 Ω termination resistors
Complies with JEDEC standards:
